找到 reCAPTCHA 元素并单击它 -- Python + Selenium

Find the reCAPTCHA element and click on it -- Python + Selenium

我需要一些帮助。 有URL：https://www.inipec.gov.it/cerca-pec/-/pecs/companies。 我需要点击复选框验证码：

我的代码是这样的：

import os, urllib.request, requests, datetime, time, random, ssl, json, codecs, csv, urllib
from urllib.request import Request, urlopen
from urllib.request import urlretrieve
from datetime import datetime
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import NoAlertPresentException
from selenium.webdriver.chrome.options import Options

chromedriver = "chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
chrome_options = webdriver.ChromeOptions()
driver = webdriver.Chrome(executable_path=chromedriver, chrome_options=chrome_options)
driver.get("https://www.inipec.gov.it/cerca-pec/-/pecs/companies")
driver.switch_to_default_content()
element = driver.find_elements_by_css_selector('iframe')[1]
driver.switch_to_frame(element)

driver.find_elements_by_xpath('//*[@id="recaptcha-anchor"]/div[1]').click()

执行过程中出现错误：

driver.find_elements_by_xpath('//*[@id="recaptcha-anchor"]/div1').click() AttributeError: 'list' object has no attribute 'click'

请帮助修复它。

解决方案更新（2020 年 2 月 11 日）

使用以下一组二进制文件：

  • Selenium v​​3.141.0
  • Chrome驱动程序 v80.0
  • Chrome 版本 80.0

您可以使用以下更新的代码块作为解决方案：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get("https://www.inipec.gov.it/cerca-pec/-/pecs/companies")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name^='a-'][src^='https://www.google.com/recaptcha/api2/anchor?']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//span[@id='recaptcha-anchor']"))).click()

原解

在 URL https://www.inipec.gov.it/cerca-pec/-/pecs/companies 中调用 reCAPTCHA 复选框上的 click() 您需要：

  • 诱导 WebDriverWait 以获得所需的 框架并切换到它.
  • 诱导 WebDriverWait 使所需的 元素可点击。

  • 您可以使用以下解决方案：

    from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.chrome.options import Options

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe', chrome_options=options)
driver.get("https://www.inipec.gov.it/cerca-pec/-/pecs/companies")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name^='a-'][src^='https://www.google.com/recaptcha/api2/anchor?']")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//span[@class='recaptcha-checkbox goog-inline-block recaptcha-checkbox-unchecked rc-anchor-checkbox']/div[@class='recaptcha-checkbox-checkmark']"))).click()

我解决了这个问题，你可以用你的登陆网站试试这个url。

from selenium import webdriver
from selenium.webdriver.support.select import Select
from selenium.common.exceptions import SessionNotCreatedException

options = webdriver.ChromeOptions()
prefs = {"download.default_directory": download_dir}
options.add_experimental_option("prefs", prefs)
options.add_argument("--no-sandbox")
    
driver = webdriver.Chrome("/usr/bin/chromedriver", chrome_options = options)
driver.get("https://www.google.com/recaptcha/api2/demo")

driver.maximize_window()
price = driver.find_element_by_xpath("//div[@class='g-recaptcha']")
price_content = price.get_attribute('innerHTML')
start = str(price_content).find(";k=")+len(";k=")
end = str(price_content).find("&co")
driver.implicitly_wait(20)
driver.execute_script("document.getElementById('g-recaptcha-response').style.display = '';")
recaptcha_text_area = driver.find_element_by_id("g-recaptcha-response")
    
recaptcha_text_area.clear()
recaptcha_text_area.send_keys(price_content[start:end])
    #.....................................................................................
    
button = driver.find_element_by_id("recaptcha-demo-submit")
